This setup is broadly balanced for this model.
Shared-memory contention still exists
The OS, browser, and inference runtime all compete for the same physical memory pool, so real-world headroom is less forgiving than raw capacity suggests.

Inference speed
Estimated decode speed (tokens/sec) for glm 4 9b chat 1m at Q4_K_M across popular GPUs and Apple Silicon, using the fastest local runtime per device. Fastest is RTX 5090 32GB at ~126 tok/s. Speed is memory-bandwidth bound, so cards that fit the whole model in VRAM run far faster than ones that offload to system RAM.

Yes, MacBook Pro M3 Pro 18GB can run glm 4 9b chat 1m with a C grade (Runs well). Expected decode speed: 19.9 tok/s.
glm 4 9b chat 1m (9B parameters) requires approximately 9.4 GB of memory with Q4_K_M quantization.
The recommended quantization for glm 4 9b chat 1m is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M3 Pro 18GB, glm 4 9b chat 1m achieves approximately 19.9 tokens per second decode speed with a time-to-first-token of 9707ms using Q4_K_M quantization.
For coding workloads, glm 4 9b chat 1m on MacBook Pro M3 Pro 18GB receives a C grade with 19.9 tok/s and 70K context.
On MacBook Pro M3 Pro 18GB, glm 4 9b chat 1m can safely use up to 70K tokens of context. The model's official context limit is —, but available memory constrains the safe maximum.
Not always. MacBook Pro M3 Pro 18GB can often fit larger models thanks to unified memory, but a discrete GPU with dedicated high-bandwidth VRAM may still decode faster once the model fits. For this combination, the important distinction is capacity versus sustained throughput.
